The angles A and B are alternate interior angles, and as such their measure is the same.

This leads to the equation

$8x+6=4x+38$

Subtract 4x and 6 from both sides to get

$8x-4x = 38-6$

which simplifies to

$4x = 32$

Plug this value for $4x$ in the expression for $B$ to get

$B = 4x+38 = 32+38 = 70$

Which of the following is a solution of x2 + 2x + 8?

zubka84 [21]

Using the quadratic equation we get:
$\frac{ - 2 + - \sqrt{4 - 32} }{2} = \frac{ - 2 + - \sqrt{ - 28} }{2}$

Factoring out 2 we get
$\frac{ - 2 + - 2\sqrt{ - 7} }{2} = - 1( + - ) \sqrt{ - 7}$
Factoring out the imaginary number:
$- 1 + \sqrt{7} i \: (and) \: - 1 - \sqrt{7} i$
So b.
